The source of Boyd’s injury is unclear, but his last shift on Tuesday ended when he blocked a slapshot by defenseman Vince Dunn late in the third period.

Tuesday's 4-0 win over Blues took a toll on the #Caps. Center Travis Boyd is expected to miss some time a lower body injury, and is listed as week-to-week. Defenseman Michal Kempny is day-to-day with an upper body injury.

Boyd was likely to be on the #Caps' opening night roster, so if he opens the season on IR, it could open the door for another player to land an Oct. 2 roster berth, depending on how many forwards the Caps opt to keep.
